Microsoft JET Database Engine error '80040e14'

程序出错提示：Microsoft JET Database Engine error '80040e14'

Syntax error (missing operator) in query expression 'tid='.

/news.asp, line 13

第13行错误代码：<%
dim id
id=request.QueryString("id")
str="select top 1 * from news where tid="&id&" order by id desc"
set rsf=conn.execute(str)
if not rsf.eof and not rsf.bof then
%>

Microsoft JET Database Engine 错误 '80040e14' 语法错误 (操作符丢失) 在问题在这里： request.QueryString("lx")&" "&sslj 如果这里是空，sql

select top 5 * from (select * from yenews where id="" order by newsid desc) access不支持这种查询方式,sql server支持
